Embodiment 1

[0017] Example 1: 42% fenazaquin diafenthiuron wettable powder

[0018] Fenazafen 40.40g

[0019] Diafenthiuron 2.11g

[0020] Sodium lauryl sulfate (wetting agent) 3g

[0021] Alkyl naphthalene sulfonate formaldehyde condensate (dispersant) 5g

[0022] Kaolin (filler) up to 100g

[0023] The active ingredients, various additives and fillers are fully mixed according to the ratio of the formula, pulverized and sieved by a jet mill to obtain a 42% fenazaquin · diafenthiuron wettable powder. (The mass ratio of fenazaquin and diafenthiuron is 20:1)

Embodiment 2

[0024] Example 2: 22% Fenazazafen·Diafenthiuron Suspension Concentrate

[0025] Fenazazafen 20.20g

[0026] Diafenthiuron 2.11g

[0027] Lignosulfonate (dispersant) 4g

[0028] Ethylene glycol (antifreeze) 4g

[0029] Silicone oil (defoamer) 0.4g

[0030] Deionized water make up to 100g

[0031] According to the requirements of the formula, add the pre-crushed original drug, carrier, surfactant, antifreeze, water, etc. into a sand mill, grind it finely, and then mix it with high-speed shear to prepare a suspending agent. (The mass ratio of fenazaquin and diafenthiuron is 10:1)

Embodiment 3

[0032] Example 3: 24% fenazaquin diafenthiuron microemulsion

[0033] Fenazazafen 20.20g

[0034] Diafenthiuron 4.22g

[0035] N-methylpyrrolidone (solvent) 10g

[0036] Calcium dodecylbenzenesulfonate (emulsifier) ​​8g

[0037] Triphenylethylphenol polyoxyethylene (emulsifier) ​​5g

[0038] Deionized water make up to 100g

[0039] Add the original drug, co-solvent and emulsifier together to dissolve into a uniform oil phase, slowly add to water under stirring, then rapidly invert the phase after stirring and heating, and cool to room temperature to prepare a microemulsion. (The mass ratio of fenazaquin and diafenthiuron is 5:1)

Abstract

The invention discloses a fenazaquin-containing acaricidal composition. The acaricidal composition comprises fenazaquin and diafenthiuron serving as active ingredients, wherein the mass-portion ratio of fenazaquin to diafenthiuron is between 20:1 and 1:80. The compounding of fenazaquin and diafenthiuron has obvious synergism and can reduce dosage and delay the generation of the drug resistance ofpest mites. The composition can be used to prevent and control the pest mites on fruit trees, cotton, vegetables and flowers and other crops.

Description

technical field [0001] The invention relates to a compound acaricidal composition, in particular to an acaricidal composition containing fenazaquin. Background technique [0002] Fenazaquin: English common name Fenazaquin, chemical name: 4-tert-butylphenethylquinazoline, molecular formula: C 20 h 22 N 20 . Its structural formula is: [0003] [0004] The drug is a quinoline acaricide, which acts on the mitochondria and chromosome group 1 of insect cells through contact killing, occupies the junction point of coenzyme Q, and has a good control effect on citrus and apple spider mites. Natural enemies are safe. No cross-resistance with existing acaricides, especially suitable for controlling harmful mites resistant to existing acaricides. However, under the selection pressure of single-dose and large-scale application, pest mites are prone to develop resistance to a single dose of fenazazak, and the cost of controlling resistant pest mites with fenazazak is relatively ...
